Several atyid specimens were collected from hill streams in Guangdong Province, Southern China and Hong Kong during fieldtrips between 2004 and 2013. Some of these species, most of them also sold as ornamental pet shrimp in the international aquarium trade, proved to be new to science by morphological observation and analysis of mtDNA sequences. Three new species, Caridina logemanni n. sp., Caridina mariae n. sp. and Caridina conghuensis n. sp., all of them members of the so called Caridina serrata species group (Cai & Ng 1999) are described in detail below. Caridina tumida Wang, Liang & Li, 2008 is synonymised with Caridina venusta Wang, Liang & Li, 2008. Caridina meridionalis Wang, Liang & Li, 2008 is moved to the genus Paracaridina Liang, Guo & Tang, 1999 and synonymised with Paracaridina zijinica Liang, 2002. New records for Caridina trifasciata Yam & Cai, 2003 and Caridina serrata Stimpson, 1860 are recorded. All species are compared to their morphologically closest congeners and the phylogenetic relationships between atyid shrimps from Southern China are shown.
2004年至2013年野外考察期间，在中国南方广东省的山间溪流以及香港采集到了几种匙指虾标本。其中一些物种，大多数在国际水族贸易中也作为观赏宠物虾出售，经形态学观察和线粒体DNA序列分析后被证明是科学上新发现的物种。下文详细描述了三个新物种，即洛氏米虾（Caridina logemanni n. sp.）、玛丽米虾（Caridina mariae n. sp.）和从化米虾（Caridina conghuensis n. sp.），它们均属于所谓的锯缘米虾物种组（蔡 & 吴，1999）。2008年的膨腹米虾（Caridina tumida Wang, Liang & Li）被认定为2008年秀丽米虾（Caridina venusta Wang, Liang & Li）的同物异名。2008年的南方米虾（Caridina meridionalis Wang, Liang & Li）被转移至拟米虾属（Paracaridina Liang, Guo & Tang, 1999），并认定为2002年紫金拟米虾（Paracaridina zijinica Liang）的同物异名。记录了2003年条纹米虾（Caridina trifasciata Yam & Cai）和1860年锯缘米虾（Caridina serrata Stimpson）的新记录。将所有物种与其形态上最接近的同属物种进行了比较，并展示了中国南方匙指虾之间的系统发育关系。
